Some parts of the body like skin, nose, eyes, gastrointestinal tract and lungs, are susceptible to allergic symptoms although these vary from person to person and allergic condition.
• Allergic Rhinitis, also known as “hay fever,” is the most common allergic condition. This happens when there is an allergic inflammation in the nasal airways. Common symptoms include sneezing, stuffy nose, excess nasal secretion and itchy nose, ears, eyes, and throat.
• Asthma is an allergic reaction affecting the respiratory airways. This happens when there is an inflammation, constriction of airway muscles and reversible muscle obstruction. Common symptoms include coughing, chest tightness, panting, and shortness of breath.
• Allergic Eyes, also known as conjunctivitis, happens when the conjunctiva, outermost layer of the eye and the inner surface of the eyelids, experience inflammation. Common symptoms include swelling of the conjunctiva, watering itchy eyes, and redness of the eye.
• Atopic Dermatitis, also known as eczema, happens due to a complicated inflammatory process. It is not caused by a direct allergen contact, but rather, resulted from other allergic reactions that the body may be experiencing. Common symptoms include itching dry skin and rash anywhere in the body but commonly on the face, behind elbows and knees.
• Urticaria, also known as hives, is an allergic reaction that is manifested on the skin. It is characterized by red, raised itchy welts and is normally found anywhere in the body. It can be acute or chronic.
• Anaphylaxis, or an allergic shock, happens when an allergic reaction causes enlargement of the blood vessels leading to a significant drop of blood pressure and affecting other organs in the body. Common causes of this are food, insect stings, and medications. Symptoms may include nasal congestion, hives, itchy eyes, runny nose, swelling of tongue and throat, nausea, abdominal discomfort, diarrhes, vomiting, panting, shortness of breath, low blood pressure, and passing out. This is the most dangerous allergic reaction since can cause death due to lack of oxygen.
